The effects of freeze-thaw processing on the characteristics of hot-air drying and the coefficients of moisture diffusion in Malus domeri (Bois) chev were investigated. The results showed that the freeze-thaw pre-treatments had significant effects on drying characteristics. It was found that freeze-thaw pre-treatments could significantly shorten the drying period and increasing the drying rate. Logarithmic model provided better simulation of drying curves for freeze-thaw M. domeri (Bois) chev. at different drying conditions. The results indicated that Deff increased with the increasing of times of freeze-thaw.

Design Of A Adding Liquid Instrument Control System For Sample Pretreatment, Wang Zheng-Jia, Lv Zhao-Xiong, Zhai Zhong-Sheng, Zhao Hai-Tao, He Jia-Qi, Wang Chao
Food and Machinery
When manual testing food and chemical samples, there are problems such as large pretreatment errors and low efficiency. In order to solve those problems, a adding liquid instrument control system for sample pretreatment was designed. The system adopts PLC as the main controller, and the software and hardware of the system were designed according to the control demand analysis of the pretreatment instruments. Combined the characteristics of the S-type acceleration and deceleration algorithm and non-contact liquid addition method. By controlling the acceleration of the deceleration phase during the liquid addition process for the droplet hanging on the tip falling off …

In order to understand the effect of different pretreatments on the hot air drying characteristics and quality of red rose, four different pretreatment methods ,i.e. impregnated 5% citric acid solution, 20% sugar solution, 20% NaCl and citric acid mixed solution and blanching, the pretreated petals were used as the control, to conduct comparative experiments and analysis of hot air drying. Sensory properties (color, total flavonoids, total phenols) and microstructure of red rose were examined, and combined with fuzzy mathematical comprehensive evaluation method for sensory evaluation. The results showed that drying rate of rose petals was influenced significantly by different pretreatment …

This paper deals with the investigation of ultrasound (US) pretreatment of brewer’s spent grain (BSG) as ameans of releasing fermentable sugars, and the subsequent production of ethanol from this lignocellu-losic biomass. Using response surface methodology (RSM), the influence of US power, time, temperatureand biomass loading on fermentable sugar yield from BSG was studied. The optimal conditions werefound to be 20% US power, 60 min, 26.3°C, and 17.3% w/v of biomass in water. Under these conditions,an approximate 2.1-fold increase in reducing sugar yield (325 ± 6 mg/g of biomass) was achieved, relativeto untreated BSG (151.1 ± 10 mg/g of biomass). In …
